Overview
ETE Centro Paulo Afonso serves approximately 83,210 people in Paulo Afonso, Bahia, Brazil. The plant operates under Brazil's national wastewater regulations for medium-sized agglomerations.
ETE Centro Paulo Afonso is a municipal wastewater treatment plant located in the Rodoviário district of Paulo Afonso, Bahia, in northeastern Brazil. The facility serves an estimated population of 83,210, classifying it as a medium-sized agglomeration under Brazilian sanitation standards. Its location in the semi-arid Sertão region influences water management priorities. As a plant serving over 80,000 people, ETE Centro Paulo Afonso is subject to Brazil's national environmental regulations, including CONAMA Resolution 430/2011 and the National Sanitation Plan (Plansab). These frameworks require adequate treatment to protect water quality, typically secondary treatment or equivalent for urban wastewater. The plant's designed capacity is 1.00 (likely in cubic meters per second or similar unit), indicating its scale. The treated effluent from the plant ultimately discharges into the São Francisco River basin, one of Brazil's most important watercourses. The São Francisco River flows eastward through the semi-arid region, supporting agriculture, hydropower, and biodiversity, before emptying into the Atlantic Ocean. The plant plays a key role in protecting downstream water quality and aquatic ecosystems.
Environmental context
The plant discharges into the São Francisco River basin, which drains a vast area of northeastern Brazil and flows into the Atlantic Ocean. The river supports diverse aquatic life, including migratory fish species, and is a critical water source for irrigation and human consumption in a region prone to drought. Protecting water quality in this basin is essential for maintaining ecological balance and public health.
